lmprovenients in Nonskid Devices of which the following is description reference being` had to the accompanying drawings, which are `a part of thisspeciication.

The present invention relates to certain new and useful improvements in attaching member fornon-skid devices of a character i wherein a cha'in is attached to thevehicle wheel and extends about the 'tire so as to lie between the Contacting surfaceof 'the tire and 'the road-bed. j g

One object of the present invention is to provide an improved attachin; memberfor non-skid members so that the chain may be.

1% readily detached when desired and so constructed that .the terminal eyes orlinks of the tread member provide 'the means for securing the attaching member uponthe wheel.

Another object of this invention is to pro- 23 vide an attaChing device of the class described formed of spring wire andengageable about a spoke of the wheel and pro.- vided with attaching hooks -for retainin'g v a terminal link or eye of a tread member in position and at the same time securing the attaching member upon the` wheel spoke.`

A further object of the present invention is to providean'improved form of tool for use inconnection with my attaching mem-J ber forasssting'in the securement ot the' 5 same to and detachnent from thewheel spoke. a y

With the above and other objects in View which will appear as the description proceeds, my invention resides in the novel construction, combination and arrangement ot' parts substantially as hereinafter 'described and more particularly defined by the appended claims, it being understood thatsuch .herein disclosed invention may be made as come within the scope of the claims.

In the accompanying drawing I have il` lustrated one complete example of the phys ical embodiment of my invention Constructed according to the best mode I have so far devised forthe practical application of the princples thereof, and in which:

Figure l is a view taken through a portion of 'a rim of a vehicle wheel on the plane inby 'thel 'resiliency of the material 'of which themembers are constructed, and have their changes in the precise embodiment of the fAs illustrated in Figs. 1 and 2, two a idicated bythe nn; 141 oi Fi iir Q wheel being equipped with my invention;

Figure 2 is a 'View part in section and part ;in elevation taken on the line 2-2 of Figure 1;

'Fignre 3 is a perspectiveview otone iof my attachng members and the tool einployed in connection-therewithy- Figure l is a perspectve View of one end" of a tread member llustrat'ingthe improved link oreye' which' pro? form -of terminal vide; and

V Figure is a plan view of one ofthe ati taching 'members illustratinga slightlyflmod'- ified form'of Construction, the vehicle spoke hicle wheel felly,- 6 a 'tire rimsecured to 'the v to whichthe -member -is e attached being u shown in sectioni outer surface thereofiand 7 a tire which in therpresent instance is illustrated 'as being a pneumatic tire. My devce'includes two e complementary attaching members adapted' y to engage about any one' of the spokes 8 ot the wheel and each includes a single length i of-sprinr wire bent to provide a substan-` tially U-shaped inner' portion 9 which isengageable about the wheel spoke and having' i e the outer portion of the endsyof the U direct:

ed outwardl y from the edgesotthe felly and then radially as -10 and as clearly shown in Figs; l and 3. l I i The portions 10 arenormlly urged apart' extreme ends bent inwardly to provide hooks ll'over whichis engaged the terminal link 7 or eye '12 of a tread member 13. The terminal eye 1 2 is' substantially V -Shaped i andis retainedupon the hooks 'of the attaching member by the pressure of the portions 10' thereotf whichlare normally urgediapart before: described. i

tachng members. are' provided for each' tread member. 13, theportions 10 of one' attaching member being positioned 'at one side ofthe wheel and the portions 10 of the other being positioned at the opposite side thereo'i the wheel spoke by springing the portions 10 'The attaching membersare engaged aboutf v by means of a substance 14 such as rubber, 1

be m ereome bv the pressing' of the same to- ;'ether lov the &me I pro an improved t form of tool to permit the springing of the same together 'for ttaching or detaching the ad'acent terminal eve 12 which tool consists' of lever having; its inner end .notched as at 16 for engagement With one portion andhavin; its other end providing an Operating' handle 17. the lover adjaeent its inner end is a link 19 having; its free end notched as at 20 for enga'ement With the other portion 10, and Wlih the portions iOpositioned in thenotehes %and 20, an outxvard pull on the hendle 17 will force the portons i together'and permi? the reav attachment to or removal from the hooks 11 ofthe ad" .cent terminal link.

As will be readilyo` one to those skilled in theart to which an intention ot char acter appertains I have devised an ttaohing tor non-skid `ehains ortreadflmem bers which is extremely simple in constrution butpracticel in operation apd I have also provided a tool for use in onnection therevith for facilitating the ready attachment to or detachment from the attaehing members ot' the terminal linlis of a tread emb e f In 5-1 have illustrated ;i slightly .modified form of my invention in which one of the end' portions 10 is hooked or looped, as at 21 lonqitudinally with respect to the vehicle wheel and the other end portion ot which is direete-dlongitudinally as at 22,

With respect ,to the wheel to close the throat or" the hook 21. The extreme end of the hooked portion is looped, as at 23, for detachable engagement With the other end por t ion 10, and With the hooked portion. 23 en.- gaged :vit-l the end 10, ,the terminal eye 13"' of the tread member Will be ecured on the hool 21.. Te permit the disengegement of theterminal eye 1 3' {rom the hook 21, the

Pivoted at 1 8 to one side ot the wheel With the extremities th sroot from which it is seated, the legs of said memrojecting on the side opposte that ber normailv tending to spring away from each other: one of said legs having a hook adapted to be engaged hy the terminal link ot a chain, the extremity of the other of se d' lee e being; bent around and' provided 'With a hoqi: adapted to engage the first mee tioned therebv holding the legs closely together and clamping the member tightly about the spoke.

A device of the class described comprising; a U-shaped resilient member ada'pted tobe seated about the spoke of a wheel from one side the wheel ith the extremitles thereof projeeting on the side opposite that from which it is Seate cL the legs of seidmem ber normally tending to spring away -from each other; one of said legs having a hook adapted to be engaged by the terminal 'link of a the extremitv of the other of said lers being' bent around and provided'wi'th a hook adapted to engage the' first mentioned leg. therebv holding the legs eljosely'together and clamping' the member tirhtly about the spoke.` said bent around portion ot the second mentioned leo; substantiallv closin'g the threat of the hooi: provided on the first mentioned legend preventin disengagement of the lini: from the hook.. i
